1)   Mount ring 20 so that it's tapered side contacts spindle.
2)   Mount collar pin 20 so that it's width across flat faces spindle.
3)   Mount thrust needle bearing 821 so that washer that has a bigger outer diameter should be on helical gear 46 side.
4)   Mount oil-less bearing so that it's chamfering side faces the front tip.
